Really stretching my memory here, but…
I do remember there was defintely a lever that had to be pushed from the outside through a gap in the shell while the two halves were clipped together. Can’t recall just looking at your photos. 
Probably not much help to you… Damn, it’s been a long time since I looked at the insides of an old pre-V2 Le Hui. 
Yeah I think it is that one right there in the last photo
A bit of a pain in the ass to do, will probably try again after work as it seems to need pressure both sides to allow it to clip together properly
But nah mate you’ve been more than helpful
Much appreciated 
This LH Hk416 gearbox is a pain in the ass, so fiddly and with my fiddle fingers it’s an absolute headache
I’ve managed to get it aligned how it needs to be, but as soon as I put the trigger spring in, it comes out of alignment and fails if I continue as is.
For the life of me I just can’t get it to stay how it needs to in order for it to function correctly
Notice how it’s not sitting correctly as soon as the spring goes in
Any tips would be greatly appreciated, cheers
That bottom photo is correct. That’s where the lever needs to be to push the trigger trolley.
Pretty sure you need to push that lever up into the safety position above the trolley as you snap the two shell halves together. There’ll be an audible click.
When I have that piece in this position
It doesn’t engage this cog at the back
Like the lever at the back isn’t making contact with the cogs to release the gears or whatever it’s purpose is, it’s not contacting anything else and hence its still not firing
Getting over pulling the gearbox apart. Done it around ten times now, no luck 
If I had the thing in front of me it’d be sorted, no problem. Just been so long the photos aren’t sparking anything in my melon memorywise.
Chuck it in a bag, mail it to me. I’ll sort it and mail it back to ya.
Modified a BigRRR MP5 handguard to fit my Scorpion EVO. Better looking than the previous Magpul unit.
Still have to sort the torch out with a pressure pad and the laser is non-functional and will stay that way, also need to clear a little away to allow fitment of the drum mag. But the sucker will house a huge brick of a lipo comfortably and looks pretty tacticool, IMO. 
Just sweating on the day when I can get my hands on a shell from an ASG CZ Scorpion EVO3… the airsoft unit. 
Time to give the ol’ Ze Hua F2000 a little love today.
Screws are coming out, it’ll be getting 3mm threaded inserts so machine screws for reassembly instead of the stripped out plastic self tappers.
While the box is out I’ll take the opportunity to do a bit of body deadening and sound proofing on the shell, before a pimped out Singularity box goes in for the win.
With that long inner barrel it should be easy to get it up around 300FPS, and accurate. I do love the old classic blasters. 
Post Edit :
Holy shit… 75% of the screw anchor points are snapped off at the shell. 
Looks like this F2000 refurb’s going to be a bigger challenge than I thought. Damn, I wish these could still be picked up for $75 like back in the good ol’ days.
Ah well… something to do
